19 Pin Circular Feedthrough on CF Flanges
The compact and unique 19-pin Mil-C-26482 CF hermetic feedthrough design allows installation into many CF flange sizes and styles. Gold-plated pins are arranged in a straight-through pin-to-pin design and are hermetically sealed and electrically insulated in a stainless steel shell using the latest in glass-ceramic bonding technology. These feedthroughs are mounted on CF Flanges that incorporate the industry standard "captured copper gasket" sealing principle, making it easy to mount to your existing CF Flange ports.

| Notes |
- Electrical ratings are maximum test values, with vacuum side at ≤ 1x10-4 Torr. Feedthroughs are intended for instrumentation applications carrying low level signal voltage and current.
- For proper heat dissipation, a maximum of 20% of the pins on a feedthrough may carry the maximum pin current at any given time.
- PEEK is a polyether ether ketone thermoplastic.
- Leak tested to 5x10-10 Standard cc/sec of He.
- Overall assembly ratings must be adjusted to that of its lowest rated component. For cryogenic service, the lowest recommended temperature is -200°C
- Unless designated a 'kit,' connectors and cable assemblies are not included with feedthrough and must be purchased separately.
